Planul tarifar nelimitat micșorează costul suplimentar.

In Romanian, the definite article is usually attached to the end of the noun, not written as a separate word like English the.

• plan = plan
• planul = the plan

So planul tarifar nelimitat means the unlimited tariff plan or the unlimited pricing plan.

Tarifar is an adjective related to tariff / rate / pricing. It describes planul.

So:

• plan = plan
• plan tarifar = pricing plan / tariff plan

Romanian often places adjectives after the noun, so plan tarifar is normal word order.

In Romanian, adjectives usually come after the noun they describe.

So instead of English-style unlimited tariff plan, Romanian naturally says:

• planul tarifar nelimitat

Literally, this is closer to the plan tariff unlimited, but in natural English we reorder it as the unlimited tariff plan.

Both tarifar and nelimitat describe planul.

Adjectives in Romanian agree with the noun in gender and number.

Here, planul is:

• masculine
• singular
• definite

So the adjectives also appear in the masculine singular form:

• tarifar
• nelimitat

If the noun were feminine or plural, the adjective form might change.

Micșorează is the 3rd person singular present tense of a micșora, meaning to reduce, to decrease, to make smaller.

So:

• a micșora = to reduce
• micșorează = reduces

In this sentence, the subject is planul tarifar nelimitat, which is singular, so micșorează is in the singular form.

Again, Romanian usually puts the definite article at the end of the noun.

• cost = cost
• costul = the cost

So costul suplimentar means the additional cost.

Both planul and costul are definite nouns in this sentence.

Suplimentar is an adjective meaning additional, extra, or supplementary.

So:

• cost suplimentar = additional cost / extra cost
• costul suplimentar = the additional cost

Here it describes costul, and like many Romanian adjectives, it comes after the noun.

The sentence structure is:

• Planul tarifar nelimitat = the subject
• micșorează = the verb
• costul suplimentar = the direct object

So the full pattern is:

The unlimited tariff plan + reduces + the additional cost

Romanian often uses the same basic subject-verb-object order as English, so this sentence is fairly straightforward.

Yes, Romanian word order is somewhat flexible, but the version given is the most neutral and natural for a standard statement.

The normal order here is:

• Planul tarifar nelimitat micșorează costul suplimentar.

You might sometimes see changed order for emphasis, but for learners, it is best to treat this sentence as a standard subject + verb + object structure.

These are two important Romanian letters:

• ș sounds like English sh in ship
• ă is a short neutral vowel, similar to the unstressed vowel in about

So:

• micșorează is roughly pronounced meek-sho-rea-zuh
• suplimentar contains a normal a, not ă
• planul ends with -ul, roughly ool

A rough pronunciation of the whole sentence could be:

pla-noo(l) ta-ree-far ne-lee-mee-tat meek-sho-rea-zuh kos-tul soo-plee-men-tar

Not always. A micșora literally means to make smaller or to reduce, and it works well for things like costs, quantities, sizes, and amounts.

In many practical contexts, it matches English reduce very well:

• micșorează costul = reduces the cost

But Romanian also has other verbs that can sometimes translate reduce, depending on context, such as:

• a reduce
• a scădea

In this sentence, micșorează is perfectly natural.

Because costul suplimentar is the direct object of the verb micșorează.

In Romanian, as in English, many verbs take a direct object without a preposition:

• reduce the cost
• micșorează costul

So no extra word is needed before costul suplimentar.

Yes. Depending on context, plan tarifar could be translated as:

• tariff plan
• pricing plan
• rate plan
• sometimes even service plan

The best English translation depends on the situation, especially in telecom, internet, or subscription contexts. In this sentence, unlimited plan or unlimited tariff plan would often sound most natural in English.
